/usr/share/games/0ad/ EDIT: It should be located there on all Linux systems, regardless of distro. I believe there was instructions on installing new AIs over in the JuBot thread. You might want one of those.

For your convenience, I have packaged the music available on the audio page in one neat file. I might also repackage the (newer) in-game music if I have the time. Anywho, there's the audio. http://www.mediafire.com/?575bvc5siwnj1a1

Heh. Perhaps the team could team up with various retailers to offer a 0 AD team-supported version of 0 AD (when it's pretty complete) with some additional features (ie, interviews, behind the scenes, more included AI opponents, perhaps a "bonus" campaign.) in stores. At around ~$30, you probably won't scare off anybody, and odds are, the price point will attract savings-conscious buyers. Besides, a little exposure is a good thing.
